• 2 cloves garlic, minced
• ½ tsp red pepper flakes (optional, for a bit of heat)
• Salt and pepper to taste
• 4 slices provolone or mozzarella cheese

Instructions

Cook the Broccoli Rabe
Bring a large pot of salted water to a boil. Add the broccoli rabe and cook for 2–3 minutes until tender. Drain and set aside.

Sauté the Mushrooms and Onions
In a large skillet, heat olive oil over medium heat. Add the sliced mushrooms and onions, cooking for 5–7 minutes until softened and golden.

Add Garlic and Broccoli Rabe
Stir in the garlic, red pepper flakes, and cooked broccoli rabe. Season with salt and pepper. Cook for another 3–4 minutes until everything is well combined and fragrant.

Toast the Hoagie Rolls
Lightly toast the hoagie rolls in the oven or on a skillet until warm and slightly crispy.

Assemble the Sandwiches
Divide the vegetable mixture among the four rolls. Top each with a slice of provolone or mozzarella cheese. If desired, place under the broiler for 1–2 minutes to melt the cheese.

Serve and Enjoy
Serve hot with your favorite side salad or a handful of baked chips.
